WPC Flower Stand Box (Composite Trellis Planters): A Symbiotic Green Plant Carrier Integrating Climbing Green Plant Cultivation and Landscape Decoration 

WPC Flower Stand Box (Composite Trellis Planters) is designed with the concept of "symbiosis of stand and box · function integration", and realizes the triple value of "climbing green plant guidance + flower cultivation + scene function expansion" through an "integrated structure of flower stand and flower box". In scenarios such as courtyard landscaping, balcony decoration, and commercial green plant display, traditional flower boxes and flower stands often face problems such as "low space utilization due to separate use", "lack of scientific guidance structure for climbing green plants", and "difficulty in unifying landscape styles" — for example, family courtyards need to place both flower boxes for cultivating flowers and flower stands for vines to climb, but the separation of the two takes up too much space; commercial windows need to create a three-dimensional landscape of "flower stand climbing + flower box cultivation", but the mismatched styles of the stand and box affect the overall aesthetics; balcony leisure areas need to balance green plant viewing and practical functions, but lack an integrated design of "flower stand sunshade + flower box storage". The flower stand part is suitable for the growth of climbing plants such as vines and climbing roses, while the flower box part carries small and medium-sized flowers or practical modules. It not only solves the space and style problems caused by the separation of traditional stands and boxes, but also adapts to diverse scenarios relying on the weather resistance and durability of WPC materials. It has become an ideal choice for "family courtyard landscaping, commercial green plant display, and balcony leisure decoration", enabling green plant cultivation and landscape decoration to achieve a symbiotic effect of "1+1>2".

Major Advantages of the Product

✅ Symbiotic Structure Design of Integrated Stand and Box

Targeting the demand for "symbiosis of climbing and cultivation", Composite Trellis Planters innovates a "three-dimensional linkage structure":

• Symbiosis Optimization of Structure: The flower stand adopts a "grid-like frame design" (grid size 15cm×15cm), and the frame is made of thickened WPC profiles (thickness 3cm) to ensure sufficient support points for climbing plants. The flower box and flower stand are connected by "embedded connection", with the top of the flower box seamlessly connected to the bottom of the flower stand, forming a three-dimensional structure of "flower stand on top and flower box below". The height of the flower stand can be customized (conventional 1.5-2.2m), and the size of the flower box is 80-120cm (length) × 40-60cm (width) × 35-50cm (height), adapting to different scene spaces.
• Climbing Guidance Design: The flower stand frame is equipped with "adjustable climbing ropes" (made of waterproof nylon rope, adjustable length), which can adjust the angle of the rope according to the growth direction of plants to guide vines to grow upward or horizontally. The top edge of the flower stand is added with "arc-shaped guide rods" to prevent vines from falling off after growing to the edge and avoid damage to plants by sharp edges.
• Symbiosis Guarantee of Load-Bearing: The connection part between the flower stand and the flower box adopts "stainless steel reinforcement parts", with an overall load-bearing capacity of 150kg (flower stand load-bearing 50kg, flower box load-bearing 100kg), which can safely bear the weight of climbing plants and the weight of soil and flowers in the flower box. A "reinforced crossbeam" (spacing 20cm) is set at the connection between the bottom of the flower stand and the flower box to avoid structural deformation caused by long-term use.

✅ Growth Adaptation System Exclusive to Climbing Plants

Centering on the "growth characteristics of climbing plants", it optimizes the growth support structure:

• Adaptation of Light and Ventilation: The grid frame of the flower stand adopts a "30° inclined design" to ensure that the leaves of climbing plants can receive light evenly, and the ventilation rate of the grid gap is more than 80%, avoiding diseases of plants caused by poor ventilation. The flower box part adopts a "semi-open design" (5cm ventilation holes reserved on the side) to enhance the air permeability of the soil in the box, adapting to the growth of flowers that like ventilation.
• Expansion of Growth Space: The flower stand can be equipped with "extension modules" (each extension height 50cm) according to the climbing height of plants. When the vines grow beyond the height of the original flower stand, there is no need to replace the entire product, and only the extension module needs to be added. A "layered partition" can be installed inside the flower box to divide the flower box into a "upper cultivation + lower storage" space. The upper layer cultivates flowers, and the lower layer places gardening tools or outdoor decorative items, improving space utilization.
• Convenience of Growth Maintenance: The flower stand frame adopts "detachable grid pieces". When climbing plants have diseases and insect pests, the corresponding grid pieces can be removed for pruning or spraying, without overall cleaning. A "hidden maintenance door" (size 20cm×30cm) is reserved on the side of the flower box to facilitate checking the soil moisture and root growth, reducing interference to plants.

✅ Scene-Based Function Integration Characteristics

Relying on the "stand and box space", Composite Trellis Planters realizes the integration of "green plant functions + practical functions":

• Family Courtyard Functions: The top of the flower stand can be equipped with a "foldable sunshade" (made of WPC composite board, unfolded size consistent with the top of the flower stand). It can be unfolded in summer to block the sun and provide a cool area for the courtyard. The flower box part can be replaced with a "cultivation + storage" module, with flowers cultivated on the left and a drawer-type storage box (size 30cm×20cm×15cm) set on the right to store gardening scissors, watering cans and other tools.
• Commercial Display Functions: A "transparent acrylic display board" (size 40cm×60cm) can be embedded in the flower stand frame to display brand LOGOs or product information. Climbing plants grow around the display board, forming a creative display effect of "green plants + promotion". The flower box part can be equipped with an "LED light strip groove", which outlines the outline of the stand and box after being lit at night, enhancing the visual appeal of commercial windows or stores.
• Balcony Leisure Functions: A "foldable leisure tabletop" (made of WPC board, unfolded size 60cm×40cm) can be installed on one side of the flower stand, which can form a small leisure area with outdoor seats. The flower box part can integrate a "small refrigerator" (capacity 20L, with thermal insulation layer) for storing drinks and fruits to meet the needs of balcony leisure. All functional modules adopt a "plug-in design" and can be flexibly replaced according to scene needs, adapting to different usage scenarios.

✅ Durable Protection System for Full Scenarios

Aiming at different scene environments, Composite Trellis Planters builds a "multi-dimensional protection" system:

• Material Protection: Adopting "high-density anti-aging WPC material" (density 1.3-1.4g/cm³), the surface is added with "anti-UV coating + anti-fouling coating". It has no fading (color difference ΔE ≤ 1.7) or embrittlement after 6 years of outdoor use, and stains can be directly wiped with a damp cloth. The water absorption rate is ≤ 0.25%, with no penetration and expansion after rain. The material is resistant to insects and mold, adapting to humid courtyard or balcony environments.
• Structural Protection: The connection of the flower stand grid frame adopts "mortise and tenon + screw double fixing" to avoid loosening caused by long-term wind and rain. The bottom of the flower box is equipped with "thickened anti-slip foot pads" (made of rubber, thickness 2cm) to prevent the flower box from shifting and avoid scratching the ground.
• Scene-Specific Protection: The special style for coastal scenes adds an "anti-salt spray coating" to resist the erosion of sea salt in the sea breeze on the stand and box. The style for cold northern areas adopts an "anti-freezing WPC formula", with no cracking at -35℃, and no damage after 50 freeze-thaw cycle tests (-30℃ freezing for 8 hours → 60℃ thawing for 4 hours). The flower stand frame of the commercial scene style adds an "anti-graffiti coating", and graffiti can be easily removed with a special cleaning agent to maintain the display aesthetics.

✅ Low-Maintenance, Safety and Environmental Protection Characteristics

Composite Trellis Planters has significant advantages in use convenience, safety and environmental protection:

• Low-Maintenance Design: The material does not require regular painting of anti-corrosion paint or insect repellent, and daily maintenance only requires rinsing the surface with clean water every 2-3 months. The grid gap of the flower stand is large, making it easy to clean fallen leaves and dust without frequent wiping. The drainage holes of the flower box adopt a "large-diameter design" (diameter 2cm), which is not easy to block. 12-15 holes are set per square meter, with a drainage rate of more than 95% and no water accumulation.
• Safety Design: All edges and corners of the flower stand and flower box are treated with "R8mm rounded corners" to avoid collision injuries to users (especially children). The end of the flower stand climbing rope adopts a "round head design" to prevent hooking clothes or damaging the skin. If electrical modules (such as LED lights) are integrated in the flower box, they all adopt an "IPX6 waterproof design" to avoid short circuits in rainy days.
• Environmental Protection Characteristics: The raw materials adopt "70% recycled wood fiber + 25% recycled plastic + 5% plant flame retardant". The production of 100 sets of flower stand boxes can reduce 1.6 tons of plastic waste and save 1.2 cubic meters of wood. The production process has zero formaldehyde emission, and the product can be 100% recycled and reused after scrapping, in line with the concept of "green environmental protection".
